Abstract
An optical device for the stabilization of images, including a first deformable membrane and a second deformable membranes, a support to which a respective peripheral anchoring area of each of said membranes is connected, and a constant volume of fluid enclosed between the first and the second membrane, said fluid producing mechanical coupling of said first and second membranes. The optical device also includes: a first actuation device of a region of the first membrane located between the peripheral anchoring area and a central part of the first membrane; and a second actuation device of a region of the second membrane located between the peripheral anchoring area and a central part of the second membrane. A control means of the first and second actuation devices is configured, from a rest position where the first and second actuation devices are inactive, to have multiple operating modes to apply respective actuation voltage to the first actuation device or the second actuation device.
